摘　　要：新生代,中国东部大陆边缘系统总体受到来自印度、澳大利亚、菲律宾和太平洋板块向欧亚板块下部俯冲碰撞的作用,在大陆边缘形成一系列边缘海盆地和断陷-坳陷盆地,主要发育松辽、渤海湾、江汉、苏北、东海、珠江口和北部湾等盆地.基于中国东部沉积盆地的中生代构造背景分析和新生代盆地的分布特征,对其中的7个主要沉积盆地进行了详细的沉积序列和构造演化分析.通过周缘板块和郯庐断裂的构造演化、火山活动、低温热年代学、气候演变等对比分析,中国东部沉积盆地的演化可划分为3个阶段:古新世-始新世、渐新世-早中新世和晚中新世-第四纪.With subduction collision between Eurasian plate and surrounding plates such as Indian,Australian,Philippine and Pacific plates,a series of marginal sea basins,and faulted-downwarped basins formed in the continental margin of eastern Chi-na,mainly including Songliao,Bohai Bay,Jianghan,Subei,East China Sea,Pearl River Mouth and Beibuwan basins.Based on Mesozoic tectonic background analysis and Cenozoic distribution characteristics of sedimentary basins in eastern China,sedi-mentary sequence and tectonic evolution of 7 main basins are analyzed in detail .through a comparative study of tectonic evolu-tion of the surrounding plates and the Tan-Lu fault,volcanism,low temperature thermochronology,climatic evolvement,and so on.It is found that the tectonic evolution of the sedimentary basins in eastern China can be divided into three phases,which are Paleocene-Eocene,Oligocene-Early Miocene and Late Miocene-Quaternary respectively.
